' v SELF CLEANING BAIHTUE Application filed Beptember ing is a specification.

This invention relates to bath-tubs, one of its objects being toprovide slmple and eflicient means whereby, when it is desired to clean the tub, the opening of a valve will result in the'discharge of small jets'of water from the rim portion of the tubagainst the opposite wallof the tub so that. any accumulations on thesurface of the tub will be washed downwardly toward the outlet.

A further object is to provide a bath tub which .is practical to produce, it being understood that the improvements constituting the present inventlon can be built into a tub of special construction or into a hood attachment to be applied. to an. ordinary bath tub.

With the foregoing and other objects in view which will appear as the description roceeds, the invention resides in the comination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the inventlon herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

.In the accompanying drawings the preferred form of the invention has een shown.

In said drawings,

Figure 1 is a vertical longitudinal section through a specially constructed bathtub havingthe present improvements combined therewith.

Figure 2 is a section on line 2-2 Figure 1. Figure 3 is tin-enlarged section through the rim portion of the tub.

Figure 4 is a face view of a portion of the tub. showing one or the openings over which the apertured plate is to' be secured.

,Figure 5 is a section through a hood adapted to be applied to an ordinary bath tub, said hood having the present improvements combined therewith. v.

Figure 6 is a view showing in detail a means for controlling the flow, or water to the'rim of the tub. a v

Figure 7 is a transverse section through a .portions of the tub and 1100 24,1925. Serial No. asses.

' bath tub having cleaning means atone side only.

Referring to the figures by characters of reference 1 designates a bath tub one end portion of which is extended upwardly to constitute a hood or honsin 2. The rim are cast holoW so as to provide a water conducting passage 3 extending continuously along the rim, Qpening into this passage are pipes 4 havmg a branch pipe 6 which opens into a spraying nozzle 7 supported within oragainst the bottom wall of the overhanging portion of hood 2. A valve ,8, may be pro vided for controlling the flow of water to the nozzle 7.

The pipes, 4 and their connections are preferably located between the upper and lower walls of the overhanging portion 9 of the hood and thesepipes can be extended outwardly from said overhanging portion where they are joined to hot and cold water supply pipes 11 and 12 each of which can be provided with a valve 13'having its handle 14 arranged within a recess 15 in one of the upstanding walls of the. tub.

From the foregoing it will be apparent that water can flow within pipes 1 1 and 12 through the open valves 13 to the respective pipes 14. By opening the valve 8 water Will'not only be directed into the passage 3 but will also be directed to the, nozzle 7. The valves 14 provide a means whereby the occupant of'the tub can control readily the how of watento the nozzle and to the pas- Saga 3.

Located at the foot of the tulo is a water inlet 10 controlled by mixing valves 16.

This, inlet has supply pipes 5 leading thereto and a branch pipe 6' communicates with thesupply pipes and opens into the hollow rim of'the tub. A mixing valve 8 controls the flow throu h the branch pipe.

Formed wit in the inner wall of passa e ,3' is a series of slots 17 extending longitu inally of the passage, each of these slots being provided with a continuous recess in thewall thereof as shown at 18 thereby to provide a continuous shoulder. 1

Narrow webs or connecting strips 19 are located between the slots and are provided with apertures 20 tor the reception of Eastening' means hereinafter explained. By referring particularly to Figures 2 and 3 it Extending longitudinally of the slots are a desirednumber of stri s 21 of metal or any other suitable material which will not corrode, these strips being adapted to fit sun 1; within the recesses 18 and being fastene 111 place by bolts 22 or the like extending through the strips and through the apertures 20. Each of these strips 21 is provided with a plurality of small apertures 23 so arranged as todirect jets of water downwardly and inwardly from the strips and against the opposite sides of the tub.

, Thus it will be seen that when the valves are opened the jets of water will be directed from the pa 3 through the apertures 23 and against t e opposite sides of the'tub so as to wash down the sides and remove therefrom all accumulations.

' Importance is attached to the fact that the innerwall oi the passage 3 is formed with elongated slots. lit is thus possible to readily construct the tub whereas, should the tub be formed with small o enings in its walls the construction thereo would be practicallyimpossible. Instead of providing small openings in the tubthe apertured strips 21 are employed, these strips fitting spigly in the recesses 18 so as to bridge the s o s. n

It is to be understood, of course, that if desired a detachable hood section 24 can be mounted on one end portion of the tub, this hood section bein provided with an apertnred strip 25 which extends across slots formed in the inner wall of the passage 26 formed in the rim of the hood.

' Furthermore it is to be understood tha if desired, an .apertured strip a: can be located at only one sideol the-tub, as shown in Figure 7 wherein. the water receiving passage '28 only extends along the rim and one side of the tub.

As before stated the construction or the bottom, wall of each passage is such that water. will not be trapped therein but all of the liquid contents of the passage can drain therefrom. In this connection see particularly Figure 3 of the drawing.

What is claimed is:

1. A bath tub having an overhanging hood portion, there being a passage within the rim of the hood portion for the reception of water, said passage being provided with spaced longitudinal slots opening through t e innerwall of the hood portion, means for directing water into the rim, and an apertured plate flush with the inner surface.

of the hood portion and bridging the slots,

said plateconstituting means for directing jets of water inwardly and downwardly against the opposite wall of the hood portion and tub.

2. A bath tub having a hOllOWIliIl provided with spaced slots extending longitudinall oi the inner surface of the rim, the wal s of the slots being recessed, means for directing water into the hollow rinn'an apertured plate seated in the recesses with its inner surface flush with the inner surface of the wall of the tab, the apertures in said plate being positioned to direct jets oi'water inwardly and downwardly against the op posed wall of the tub. v

3. A bath to "having a hollow rim provided with longitudinal slots, the bottom wall of the passage within the rim being inclined downwardly to the lower walls of w the slots thereby to drain through the slots, there being rccessesalong the walls of the slots, webs connecting opposed walls of the slots, a plate seated in the recesses and detachably secured the webs, said plate having its inner surfaceflusb with the inner surface of the wall of the tub, there being apertures in the "plate for directing jets of water downwardly and inwardly against the opposite wallet" the tub.

In testimony that I claim the foregoing as my own, l have hereto aiiixed my signature.
